PROOF-TAKING ROLLER MAcHlNE.

srucrrrcn'rrorv forming part of Letters Patent Nasaoae, dared ANwember 2, 1886.

To aZZ whom it may concern: p

Be it known that I, `ARTHUR LEE EAsrIN, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Proof- Taking Roller Machines,ofwhich thefollowing'isafull,clear,and exact description, reference being had to the accompanying drawing, forming part of this specification, and inwhich the ligure is a perspective view of my proof-taking machine, with part broken away to show the means of attachment of the spiral-spring shalt which carries the knife, and represents the manner of operating the machine.

My invention relates to a machine for taking proof hectograph copies; andv my invention consistsin features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawing, A represents one of my proof-taking machines, B the frame in which the roller runs, and C the handle, the manner of grasping which is shown by the operators hand in dotted' lines at D.

E represents the main shaft'or axle on which the roller runs. It works in bearings -F n'ear the lower extremity of the pendent arms B'z of the frame B. A cylindrical sleeve, G. surrounds the shaft E, and serves as a bobbin on which the paper roll H is wound. This roll can either be filled on the machine by frictionrolling, or may be `illed by any suitable machine for winding rollsr preparatory to its in- .sertion in the frame.

H is the paper composing the roll. Inactive operations the' latter mode of filling is preferable, as a number of the bobbin-sleeves can thus be filled and kept in stock ready for insertion in the machine without stopping to refill the roller.

I representsV the knife, which serves the double purpose of severing the proof-sheets by its edge I', (after the impression is taken,) and as a `clamp or follower to keep the paper intact and prevent its loosening on the roll during thev process of unrolling and prooftaking. The knife-clamp is secured to a sleeve, J', that embraces and runs on a spindle-shaft, J which has bearings' K inbracket-.arms K, the said'arms being secured by rivets or screw-bolts K2 to the top bar, B', of the frame. The loop or bar L', in conjunction with the Application filed January l5, ISES. Serial No. 198,639. (No model.)

spiral springs L, that are wound around the spindle-shaft, enforces the clamping of the knife-plate against the roll.

type or the hectograph-plate from which the impression is to be taken. The machine is especially adapted both to taking proof and also hectograph copies, 8m.

By the use ot' my machine the facesof the type are not damaged, as they frequently are by hammering on the blocks in the usual manner of proof-taking; neither are the backs of the' sheets soiled, as they are by blocks, or defaced by the dirty sponge, and no deep impressions are made through the back of the proofsheets, 'for the pressure from the roller is distributed evenly `over the whole surface, having a progressive motion instead of a dead pressure, without any jar like that produced by the hammering process. required to be cut into sheets'(as in the present practice) previous to taking the impression, and in consequence does not become soiled by handling (the machine doing the handling) or wasted. by the use of a needless amount of paper, which in my machine remains clean in the roll until the impression is made, and is then readily severed .by the knife ez'ractly where required.

The operation of the machine is as follows: The paper roll is not dampened, as is necesbut is placed dry in the machine and takes a dry proof, the novel features in itsl applica! tion enablingthe proof-sheet to appropriate the ink from the type without the necessity of using the capillary attraction of moisture in the paper. The machine makes use of capillary attraction in another and more convenient way, (enabling it totake a dry proof.) The progressive action 'of the roller, like that of the pen in writing, draws on the ink in the same manner as the pen with its progressive motion distributes it. This is as truly illustrated in writ-inga single letterwith a pen as with a word, for it is well known that if a nonconduetor (such as grease, for instance) on the-paper or pen breaks the thread of the capillary attraction the flow of ink is stopped and the remainder of the letteris not pro- M represents the iiask, and N the form of sary in the customary manner of proof-taking,`

duced 3 besides which the` progressive man-v The paper is not V IOO ner of laying the proof-sheet by my roller removes the ink from the type to the sheet far more effectually than can' be done by any dead pressure, as in the present manner of taking proof. The proof-sheet roll being placed in the machine, the operator, taking hold of the handle, as illustrated by the hand in dotted lines, commences at the foot of the form and rolls the proof-sheet over the type, pressing down on the machine at the same time, and by the one operation thus taking an almost instantaneous proof, by which, although the operation is quickly performed, theimpression is also Well defined.

I have made the frame of malleable iron and the knife-blade of steel-plate and of width and proportions suitable for common proof-taking operations; but it may be made of any other suitable material and size without departing,` from the essential features of my invention.

I claim as my invention- 1. In a prooftaking machine, the combina tion of the frame B, operating-handle C, main axle E, with bobbin-sleeve G, the shaft Working inbearings F, with pendent arms B2 of the frame arranged to carry the proof-sheet roll H and distribute the sheet over the faceof the type and take proofimpressions therefrom,

allsubstantially as described, and for the purpose set forth.

2. In a proof-taking machine, the combination of the frame, bobbin-sleeve for the proofroll, with the axle on which it runs, with the knife-clamp I, andlspiral springs L on the axle J, all arranged to distribute the proof-sheet over the face ofthe type and take an impression thereof, substantially as and for the purpose set forth.

3. In a proof-taking machine, the combination of the frame with its axle, the bobbinsleeve for the proof-r0ll running in the frame, With the knife arranged to clamp the roll and sever the proof-sheets when the impression is taken, substantially as described, and for the purpose set forth.

4. In a proof-taking machine, the combination of the frame and a spindle running in the frame, said spindle arranged to carry a proof-reel, unroll the proof-sheet, andimprcss it over the face ofthe type and take proof-impressions thereof, substantially as set forth.
